Abstract: In a suction apparatus for removing lubricating dirty oil from the crankcase of internal combustion engines a vacuum tank is connected to the crankcase by a suction line via a control valve which shuts off the suction line on completion of the oil suction process.

Abstract: In a circuit arrangement for providing a periodic saw-tooth current in a coil, e.g. a kinescope deflector coil, comprising a one-way conducting device that connects the coil to a voltage source, and a controllable switching device having a control electrode connectable to a periodic pilot-pulse source that makes the switching device conductive during part of the saw-tooth cycle, the switching device being connectable to a current source through an induction coil, including a capacitor that is charged by the current source by means of the induction coil when the switching device is not conductive, the improvement wherein the capacitor is connected to the primary winding of a transformer, the secondary winding of the latter being connected to the one-way conducting device, and wherein the time during which the switching device conducts and the capacitor discharges are longer than the return time of the saw-tooth cycle.

Abstract: A tool for the contact-free support of discs by gas streams impinging on discs when emerging from the supporting face of the tool at an acute angle to the disc surface, which comprises a body having a supporting face, bores within said body for connection with an extraneous gas reservoir, means in said body directed at an acute angle with respect to the supporting face for discharge of gas flowing from the reservoir, said flow-through means consisting of nozzles or recesses being position at equal distance from each other on the surface of a cone whose base is enclosed by a circle concentric with an imaginary circle on the supporting face, said circle having a diameter of 0.2-0.6 supporting face-diameters, the cone having an angle of 20.degree.-150.degree. at the apex, and wherein the distance of the flow-through means on the surface of the cone is from 2/3r.pi. to 0r, measured at the periphery of the circle, and the radial widths of the flow-through means in the supporting face are about 0.

Abstract: A process for the production of oxygen free copper castings and moldings, which contain 0.05 to 0.2% by weight of boron as micro-alloy element, by deoxidation of oxygen containing copper melts by means of calcium hexaboride, comprising introducing 0.3-1% by weight of a CaB.sub.6 into the copper melt, the CaB.sub.6 containing at least 3% C calculated on the weight of the CaB.sub.6, subsequently subjecting the cooled melt, if desired while molding the same, to a solution annealing operation and following up with a storage for an extended time.

Abstract: An improved toilet flushing assembly is provided of the type which includes a water tank, a water discharge pipe disposed at least partially within the tank, and which has an opening at the upper end thereof, defining a primary flush valve seat, a flush valve ball communicative with the flush valve seat, means for moving the flush valve ball between an open and closed position relative to the primary flush valve seat, and a generally upstanding overflow pipe disposed within the tank and having a lower open end which communicates with the discharge pipe. The improved assembly provides an overflow pipe having an opening therein disposed at a level above the primary valve seat, which opening defines a secondary flush valve seat.

Abstract: A full panel, easy-open container end closure includes a double-folded band formed in the removable panel adjacent the peripheral score, and an opening tab having a nose portion disposed adjacent the peripheral score and band. The tab is secured to a hinge section defined in the removable panel by a rupturable, bowed, generally U-shaped ancillary score which is disposed with its two ends adjacent the band and tab nose portion. This construction effectively reduces the intial rearward force required to effect panel removal.

Abstract: A can end transfer mechanism for use in a highspeed machine includes a generally horizontal base with an end-receiving pocket and a pair of can end-engaging members disposed on opposite sides of the pocket. Each of the members has an inner end portion which projects into the pocket and is dimensioned and configured to engage an opposite side of an end, so as to cooperatively constrain it against rotation in the pocket. The engaging members are resiliently mounted on the base for movement along axes which are inclined toward the vertical axis of the pocket; this facilitates insertion and removal of an end into and from the pocket, while effectively maintaining the relative lateral position of an end when received therein. The mechanism is particularly useful where proper registry of work sequentially performed on the end tends to be of critical importance.

Abstract: A container end closure includes an end wall having a removable panel defined therein by a rupturable peripheral score, and a pull tab having a nose portion at one end, a handle portion at its opposite end, and marginal edge portions which extend generally toward the end wall and terminate short of the outer end of its nose portion. At least one depressed section is formed in the removable panel of the end wall to accommodate the terminal ends of the marginal portions of the tab, upon pivoting of the tab when the handle portion is raised. This construction ensures that initial contact with the panel is made by the outer end of the nose portion of the tab, thereby maximizing the effectiveness of force applied for score rupture initiation.

Abstract: A holder for supporting a hollow article includes a base, a plurality of resilient fingers extending outwardly from the base, and restraining means for maintaining proper alignment of the fingers. The resilient characteristic and the design of the fingers permits the loading and stable seating of a hollow article presented in misalignment to the holder, and the holder is especially useful for supporting can shells which, because of the nature of the operations to be performed thereon, often cannot be externally supported.
